of Al-Mg alloy were studied after being homogenized using three homogenization technologies, i.e., 480 ℃/20 h, 430 ℃/2 h+490 ℃/12 h and 500 ℃/16 h, the corrosion performance of Al-Mg alloy sheets were tested by intergranular corrosion(IGC) and slow strain rate testing(SSRT), the fatigue performance of Al-Mg alloy sheets were tested by fatigue crack growth rate testing and Kahn tear test......

in Al phase in Al-9.6%Mg alloy increases remarkably, and those of Mg and Zn in Al phase in Al-11Mg-4.5Zn and Al-17Zn-1.5Mg alloys increase, however, the proportion of Zn saturating in Al phase.... And the lattice constant of Al phase in Al-17Zn-1.5Mg alloy changes little. Furthermore, Mg with larger atomic radius saturating in Al phase leads to the increment of the lattice constant in Al-Mg-Zn alloy......
. The strengthening of the micro-alloyed Al-Mg alloys is attributed to the precipitation strengthening by the Al3Sc particles and to the substructure strengthening. Key words: Al-Mg alloy; Al-Mg-Mn-Sc alloy...) and (d)), where it is the finest in alloy D. This suggests that addition of Mn or Sc could retard recrystallization of the Al-Mg alloys during hot-rolling, and the retarding effect is the best when Sc......
